Democrats need to discuss the likelihood that Stimulus was not big enough or well enough targeted toward small business and a possible government jobs program, not that it helped cause the deficit (and the so-called big government overspending problem).
By claiming the economic crisis was due to government overspending or corrupt government-based companies like Fannie Mae/Freddie Mac, the GOP sets the stage to privatize Medicare, Social Security and cut the government's size back to 1890-like levels.
That lack of business regulations was and is the problem underlying the recession and not the cure is being obscured by GOP on-message propaganda. Such propaganda is at best only weakly being countered by Democrats.
